Call DPP
Call DPP as I just receive mine Monster Exhaust this week for 04 Cummins. There are a few places you can get new old stock if you call around, Bank did revise the muffler last fall sometime and the new muffler is better with a resonator area built in I believe and the new double wall tip is impressive just to look at.
Search for DPP in site sponsors as they are the ones in Pasco, Wa that sell aeroturbines, and TAGs. I preferred to do business with a TDR supporter and I told them so. They will beat the torque and chrome price.
In fact, I left a voice message with T&C the day before I ordered my system, and still have not heard back from them, 1 1/2 weeks ago.
